Then the mixture after drying is sent into UV sterilizing chamber again, then waste straw is added in high speed disintegrator, crush 80
Mesh sieve obtains mixture A；
Step 3, tackifier, modifying agent, gypsum, water is added in homogenizer, speed of agitator is 350r/min, stirring 30
Minute, oyster shell whiting, nano zine oxide, nano titanium oxide are added, continues to stir 15 minutes, obtains mixture B；
Step 4, mixture B, epoxy glue, fire retardant, waterproofing agent, concave convex rod are prepared by mixture step A three prepared by step 2
Soil is added in homogenizer, is stirred 25 minutes, speed of agitator 250r/min, then mixture is spread in shaper, 85
At DEG C, suppressed 11 minutes to its pressure for applying 45MPa, the waste straw composite board invented.
